To aZZ'w/tom z't may concern:

Be it known that I, VnNsEL MoRAvA, a citizen of the United States, and a resident of the city of Chicago,'in the county of Cool: and the State'of Illinois, have invented certain new and useful Improvements in Cotton-Crop Cleaners, of which thel Vfollowing is a specification, reference being had to the accompanying', drawings, forming a partthereof. Y.

Thepurpose of thisinvention is to provide an improved apparatus for the purpose of cleaning a harvested cotton crop byfsep.- arating from-the fiber the hulls and vrefuse which are.- necessarily 'gathered with the Fiber. It consists inthe elements and features of construction shown` and described, as indicated in the claims.` Y

In the drawings: p

. Figure l is a side elevation of an apparatus embodying this invention.

Figure 2 is a plan view of the same.

Eigure- 3 is a detail section at the line 3 3, on Figure l. y

Figure 4 is a section at the line, 4 4, on Fioure 3.

he apparatus shown in the drawings comprises an endless conveyer, made .of woven wire, perforated metal or other;l reticulated or perforated viiexible` material, adapted for forming the endless belt of a conveyer, onto which at theentering endof v the path of travel of its uppercarrying ply, the material to be operated upon is delivered. @verhanging the middle' portion of the length of the path of travel of the operating ply there is a card-armoured endless belt whose lower ply travels near enough to the upper ply of the conveyer belt so 'that the cards of the card-armoured belt may engage theber ofthe `material carried vby the latter, picking it up and 'carryingv it around with-said card-armoured'belt to a point in the return course-of the latter` at whichV it isoverhung by a rotary brush or cardcombingl cylinder, which 'takes the fibrous m-aterial from the card-armoured belt and delivers it to a hopper or conveyer, a combing Y Patenten Mar; 14,1922.

on which said belt is carried; is closed `at the other two sides by casing-heads throughY one'of which van airr .conduit is Vconnected withthe chamber, the'conduitbeing conr-V nected with avsource of suction as the intake of a rotary fany ory blower, forn producing 'Y chamber,V causingtheair to flow up throu h Apartial vacuum in and suction through the l veyer belt below the ASame, lifting .the ber y against the card-armouredjbelt-so `as to in#l sure its being engaged thereby, thel discharge of theffan or blower being connected for delivering an airblast lup through the conveyer belt against the materialfthereon,

to drive it against the overhangingcards,V

while another branchof ,thel fan discharge directsan air blast between thetwo belts in the reverse of the' direction of inclination the lower ply of the card-armoured belt and projection of theV cardteeth -toqdrive .the `material into :engagement with said teeth; At the end ofthe pathof travelgof drum.7 there is located a' Vflexible-winged 'rof" 'torfwhose flexible `wings. constitute bats re .volving near enough to thearc ofthe Vcardarmoured belt as 'it 'passes upy around the drum to bat off the hulls and other refuse material whichmay be adhering to the fiber, the refuse falling upon the conveyer belt below and being conducted with the refuse already remaining on that belt to the discharge side thereoffwhere a suitable Yreceptacle receives it. Y

' vIn the drawing,y lis the endless conveyork y belt carried around a driving drum, 2, and idle drum, "3, whose shafts, 4 and5, respectively are journaled in ra" suitable r.frame structure, A. 6 is thepowerpulley onthe driving shaft, 4, ofthe drivingV drum, 2. 7 is a chute by which thematerial to be treatedis deliveredupon the entering end of the upper ply of the conveyor belt-,1; This conveyor belt, as above mentioned; is made v of perforated material', and imay, be either woven wire fabric or any otherasuitable flexible perforatedy or reticulated material. .8 is, the card-ari'noured belt, which carries a Vmultiplicity of longitudinal. strips of card,

8, slightly spaced apart, the intervals'` of the belt between the card being perforated as seen at 8".v The cards are mounted with their nclinedteeth or brush wireswprojectin'g forwardly. in the direction of travel of the belt, for engaging the fibrous material. 9 is the driving drum and 10`the idler drum of the card-armoured belt having shafts, 9a and 10a, respectively, suitably journaled in the frame, the shaft, 9a, havinga driven pulley, 11, for the main drive belt hereinafter mentioned. 12 is the rotary brush or cardcombing cylinder having a shaft, 13, journaled in the frame and carrying the pulley, 14, by which the said cylinder is rotated for combing or brushing the brous material from the card-armoured belt, 8, a-nd delivering intothe receiving hopper, 26. 15, 15, are the heads which complete the closure of the chamber which is otherwise enclosed by the two plies of the eard-carrying belt and the drums on which that belt is carried. 16 is the suction air conduit leading to the intake of a fan, 20, and opening through one of said heads, 15. 21 is the discharge conduit from the fan. It leads to a casing, 22, under the upper ply of the conveyor belt, eX- tending'substantially under the whole length of the lower ply of the card-armoured belt, and open upwardly-over its whole extent. This casing has a branch, 23, affording a discharge at 24, between the'conveyor belt and the card-armoured belt, for delivering an air blast longitudinally of said belts for driving the fibrous material on the conveyor belt in the opposite direction to that of the travel of thel card-armoured belt, and thereby opposite to the direction of projection of the teethor brush Vwires of the card.

17 is the shaft of the hull-and-refuse-separating batting device, being a flexible winged Arotor whose flexible wings or bats are seen at18.

19 is a pulley on the shaft of the batting device by which it is rotated. 28 represents a chute-board for directing the discharged hulls into a receptacle not shown.V

For driving all the several elements of this apparatus by a single drivingbelt, the pulleys, 6, 11, 14: and 19 are mounted on their respective shafts in the same vertical plane or zone, and in said plane or zone is a drive pulley, 30, on a power shaft, 31, at the opposite end of the system from that at which the driving pulley of the endless conveyor, 1, is situated; and driving belt, 35, encompasses said pulleys from the driving pulley, 31, by way of the pulleys, 6, 19, 14

Vand 11, inthe order named, the path of said belt making re-entrant loops for and passing around the pulleys, 19 and-*11, fordriving said two pulleys in the opposite direction fromxtlie remainder of the system, as it will be seen isnecessary in order that the bats, 18, may attack the :hulls and refuse by move- `ment .in the opposite direction from that (which they are for the time being carried by Athe 4card-armoured belt, and that the lower ply of said card-armoured belt, may have the same direction of travel as the upby moured belt from the conveyor belt. per ply of the conveyor belt, and may move in the opposite direction from the direction of rotation of the rotary brush or card-combing cylinder, 12, at the point at which the lat-y ter is designed to take the fiber from saidy card-armoured belt as described.

It will be understood that the purpose of giving the card-armoured belt higher speed than the conveyor belt, is that said belts vtraveling in the same direction at the proximate plies, the difference inthe rate of movement in the direction in which .the teeth of the card are inclined, shall be in favor of the card-armoured belt; that is, that the card armoured belt shall have a movement relative to the material on the conveyor belt forward in direction ,of projectionof the card teeth or brush wires, to cause these teeth to engage said material, and for this purpose the difference in speed between the two belts to be considered is the algebraic difference, consistingk of the airthmetical difference when the two belts travel in the same less belt conveyer; a second endless belt armed with cards overhanging the conveyer belt at an intermediate part of the carrying ply of the latter ,means for driving said belts to give theirproximate plies movement in the same direction and for giving the cardarmoured belt a higher speed than the conveyerbelt for causing the cards of the cardarmoured belt to engage with the material on theconveyer belt; and a rotary brush or card-.combing cylinder articulated with the card-armoured belt in'its return course from the conveyer belt. 2. An apparatus for the purposev indicated, comprising in combination, an endless belt conveyer; a second endless Ybelt armed'with cards overhanging the conveyer belt at an intermediate part of the carrying -ply ofthe latter, means for driving said belts to give their proximate plies relative movement for causing thecards of the cardarmoured belt to engage with the material on the conveyer belt, the conveyer belt being perforated for admitting an air blast through the upper ply of said belt for driving thel material thereon up against the overhanging ply of the card-armoured belt and means, for clearing from the cardarmoured belt the material gathered therein the return course of said card-ar- 3. An apparatus for the purpose indicated, comprising, in combination, an endless belt conveyer; a second endless belt armed with cards overhanging the conveyer belt at an intermediate part of the carrying ply of the latter; means for driving said belts to give their proximate plies relative movement for causing the cards of the cardarmoured belt to engage with the material on the conveyer belt; means for producing and directing'an air blast longitudinally of said belts into the interval between their proximate plies in the direction opposite to the travel of said ply of the card-armoured belt, for driving the material carriedby the conveyer belt into engagement With the card teeth or brush Wires; and means for clearing the material so gathered from the cardarmoured belt in its return course from the conveyer f belt.

4. An apparatus for the purpose indicated comprising in combination, an endless belt conveyer; a second endless belt armed With cards overhanging the conveyer belt at an intermediate part of the carrying ply of the latter; means for driving said belts to give their proximate plies relative movement for causing the cards of the card-armoured belt to engage With the material on the conveyer belt; the .conveyer belt being perforated throughout its length, the card-armoured belt being perforated between the cards thereof; heads closing at the remaining sides the space enclosed at four sides by the tWo plies of the card-armoured belt and the drums on Which the latter is carried, and an exhaust conduit connected with oneof said heads.

5. An apparatus for the purpose indicated comprising in combination, an endless belt conveyer; a second endless belt armed with cards overhanging the conveyer belt at an intermediate part of the carrying ply ofV giving thel Wiper the same direction of rotation as the drums ofthe card-armouredbelt;

whereby the Wiper Wings at the side toward the card-armoured belt move in the opposite direction from theV cards passingnup around'the drum; forrbatting off the hulls and refuse carried by the fiber on the cards.
